The students will appear as a follow-up to host Bill O'Reilly's interviews Tuesday night with state Sen. Susan Wagle, R-Wichita, and Jessica Zahn, a student intern for Wagle who was enrolled in the human sexuality class this semester.

On Tuesday's show, Wagle and Zahn said the class, taught by Dennis Dailey, involved showing pornography and the vaginas of young girls. Sullivan and Hein are expected to provide arguments in favor of the class.

The students were to be interviewed about 5 p.m. from the KU Alumni Center by the Kansas City Fox affiliate.

Wagle has tried to shut the class down by getting a bill approved by the Legislature to defund KU's School of Social Welfare if such a class shows obscene material. Gov. Kathleen Sebelius line-item vetoed the bill.

Wagle has said she would continue her crusade against the class while the Kansas Legislature is in its veto session this week.
